My invention r'elates'toimprovement in staging boards, the'principal objectin view being to provide asimply constructed device for easily and quickly attaching a plank toapile', pole, or similar upright, to extend laterally therefrom and provide a safe support for workmen, and which provides for swinging of the plankfhorizontally relative to the upright and is adjustable bodily around the upright to arrange the plank indifferent angularpositions around the same;

Other and subordinate objectsare' a1so.com-' v,down portions II of the top edges of the members 3 atthe front of said members, and issuitably secured thereto,whereby, as will be seen, 'said panel I is spaced below the'upper panel said plankmay be swung from side to side on said prehended by my invention, .all of which, to-

gether with the precise nature of my improvepart of this specification.

In said drawings; g '2 Figure 1 is a view and plan of myimproved staging board in its preferred embodiment,

Figure2 is a view in side elevation, Figure 3 is a view in front elevation, Figure lis a view in side elevation illustratin tached to a pile, V r

Figure 5 is a View in horizontal section, taken on the line 5-5 of Figure 2, and

the staging board is at- :ments, will be readily understood when the suc- I ceeding description and claim are read with refer ence to the drawings accompanying and forming Figure 6 is a fragmentary view in perspective of the plank. I

Referring to the drawings by numerals, my improved staging board comprises, in the illustrated embodiment thereof, a yoke l for attachment to a pile 2, or thelike, and including a pair of opposed, substantially V-shaped, side members 3,

adapted when the yoke is attached to assume upright position. Each sidemember 3 has a rear 9 and well forwardly of the same,

A staging plank I6 is pivoted at one end by a'bolt I! to the upper panel 9 in thetransverse center of said panel, withsaid end underlying the paneLfth plank extending forwardly over the panel l5 and resting thereon, whereby yoke and over the plank l5 and be supported by the panel l5v in any position in which it maybeswung, v P

A chain 18 is preferablyutilized for attaching the described yoke l to the pile 2, oneend of the chain being attached to the eye bolt 13 so that 'the chain may be extended .aroundfthe pile 2 and a selected link inserted in the slot M with the chain overlying the panel 9 as shown.

In attaching the yoke l to a pile 2, or other rounded upright, the chain [8 is first extended around the pile 2, and anchored in the notch I4 with theyoke I held so that-theplank I8 is upright andas illustrated in Figure 4. The yoke I may then be swungdown on the chain against the pile 2 to engage the notches I2 with the pile. When thus attached, the yoke is suspended from the pile and frictionally interlocked therewith.

to such modifications as fall withinthescope'of and upwardly from the bottom edge, andv a stepped, horizontal top edge presenting a high portion 1 of the same length as that of the bottom edge 4, and stepped down forwardly of the high ortion as at 8.

A pair of upper and lower, fiat panels 9, I0 extend crosswise horizontally between the high portion 1 and, the bottom edge 4, respectively, and are suitably secured to th side members to connect the same together, for instance as repre- .with an eye bolt l3 and adjacent the other end thereof with a front edge notch M for a purpose presently described. a

ceptible of modification .Without departing from the inventive concept, and right is herein reserved the appended claim.

What I claim is: In a device of the class described, a yoke to be opposed to a rounded upright comprising spaced apart side members, a pair of upper and lower rear cross members comiecting said side members and adapted to be opposed to said upright, said members each having a center edge notch therein adapted to fit part way around the upright to prevent the yoke from tilting laterally, a front upper cross member connecting the side members and a staging plank having a rear end pivoted to the upper rear cross member andunderlying the same said plank extending forwardly over the front cross member and resting thereon, and

v means to suspend the yoke on the upright, said 'means comprising a flexible element for training around said upright said element being attached at one end to one end of the upper cross member and having its opposite end detachably attached A front flat panel [5 extends across the stepped to the other end of said cross member,
